从历史上看,这种新颖的原则,首先诞生在美国于1920年,当弗雷德里克泰勒提出的想法特别关注后.接着是琼斯和拉姆森机器公司在1920年的早期,就使用了原油形式集团建立机床。 今天,成组技术的实施,通过应用结构良好的分类和编码系统和软件配套利用相似的组成部分采用成组技术 现代制造业的许多挑战所造成的日益严重的国际竞争和快速变化的市场变化 ,这是体现在以下中,已可成功地实现了由集团技术: 由于第一个因素,传统的商店组织(即部门化的过程)是变得非常低效的和过时的浪费是由路径的产品之间的各种机床部门产生的。 有必要整合的设计和制造阶段,以便缩短交货时间,从而赢得了竞争局面,国际市场。在产品设计的优点。关于设计的产品,组技术的主要好处是它使产品设计师避免“重轮” ,或重复工程努力。换句话说,它免除了可能以前被设计的产品的可能性 因为它促进存贮和工程设计容易的检索。 。 如果确实部分设计是不包括在公司的电脑档案,设计足够接近所需要的一个可以检索和修改,以满足满足要求 进一步利用成组技术是它促进标准化的设计特点,如弯道半径,倒角等,从而导致标准化的生产工具和工作藏品设备的标准化
